Who we are
Where we are
How we work
Cavotec is a multi-national group of
companies serving the following
industries: mining and tunnelling, ports
and maritime, steel and aluminium,
energy and offshore, airports, general
industry and automation. In the early
1960’s our main focus was the design
and production of motorised cable reels
primarily for manufacturers of tower
cranes, harbour cranes and mining
equipment.
Today, Cavotec is connecting mobile
equipment around the world in many
diverse applications.
The Cavotec Group consists of 7
manufacturing “Centres of Excellence”
located in Canada, France, Germany,
Italy, Norway and Sweden and by 5 local

qualities. By producing totally reliable
systems and backing them with efficient
service, we strive to create true customer
satisfaction.
Aurotac Sliprings
Specimas, a Cavotec Group company , is since 1963 engineering and manufacturing cable reels, slipring assemblies and Panzerbelt
cable protection systems for ports, marine, offshore and tunnelling applications.

A revolutionary propulsion system
Since the early 1950's, Asea Brown
Boveri (ABB) has been supplying electrical propulsion and power plants for half
of the world's icebreakers and many special purpose vessels built by Kvaerner
Masa Yard (KMY) in Finland.
AC/DC power plants and the Cyclo propulsion systems were introduced by ABB and
KMY as a new technology early in 1983.
New propulsion systems have been developed by other large companies like
Schottel-Siemens from Germany and
Alstom from France operating under different names as: Azipod (registred trade
name of ABB), SSP Propulsor (registered
trade name of Siemens Schottel) or
Mermaid (registered trade name of Alstom).
ABB Azipod propulsion system
These systems incorporate an electrical
motor azymuting (slewing) through 360 deg
installed inside the
pod. The pod itself is
installed outside the
ship’s hull.
Azipod units 35°
(Elation)
Conventional
rudders 40°
(Sistership)
The revolutionary advantages of the
system are:
• excellent manoeuvrability and dynamic performance as the propeller can
be directed in any direction within
360 deg.
• space and weight savings, no long
shaftlines, reduction gears, rudder
• fuel savings through improved hydrodynamic efficiency
• low noise and vibrations by the use of
optimised propeller wake field
• safety and redundancy

ABB azipod propulsion
Installed on top of the ABB Azipod
system, the MPS slipring system allows
the pod and propeller to rotate the total
360 degrees. It’s function is to:
• Transfer power (example 3600 Amps,
1,5 KV) from the diesel generators to
the revolving outboard electrical
motor and propeller through brushes
and rings
• Transfer auxiliary power, control
signals and data signals or optical
signals from the pod to the control
Siemens-schottel SSP propulsion
Installed on the top of the SiemensSchottel SSP System, the MPS slipring
system allows the pod and propeller to
rotate the total 360 degrees.
Its function is to:
• Transfer power (example 2000 Amps,
1,5 KV) from the diesel generators to
the revolving outboard electrical
motor and propellers through brushes
and rings
room, through silver brushes and rings
and/ or optical swivel joint.
• Transfer hydraulic, oil, water and air
necessary for the motor through a
hydraulic swivel
• Mount and support the steering angle
sensors for the ship steering system
and the visual steering angle indicator
• Function as a part of the air cooling
system of the motor
to the control room through brushes
and rings and/or inductive systems.
• Transfer water and air necessary
for the motor through a hydraulic swivel
• Mount and support the steering angle
sensors for the ship steering system
and the visual steering angle indicator

Specimas Cavotec's contribution
to a revolutionary propulsion system
In the early 90's, ABB Marine and
Kvaerner Masa Yard of Finland approached Specimas for a R & D study concerning the power, data and hydraulic transmission for a revolutionary ship propulsion system using an outboard electrical
motor instead of the traditional on line
shaft inboard diesel powered propulsion.
The 360 degrees manoeuvrability requires the installation of a slipring unit able
to transmit up to 4000 Amps at 3 kV,
data - control through optical fibers, or
conventional rings and a special multi
chanel swivel for billage, oil, grease and air.
The MPS slipring system is supplied in an IP
44 heavy robust steel housing for marine use
and is pre-wired with cables or hoses according to the customer request.
After 3 years of tests and studies first on
the Lunni ice breaking oil tanker and
after that on the Botnica, in 1995 we
received the first orders for the Fantasy
Class Carnival Corporation,
M/S Paradise and Elation.
In 1999, Siemens-Schottel of Germany
placed the first order for a similar system
to power two TT-lines ferries and the
Costa Classica cruise liners.
With a population of over 59 Marine
Propulsion Sliprings (MPS) installed all
over the world, in different type of ships
from cruise liners, to ice-breakers, ferries,
military ships, etc, Specimas – Cavotec is
today the only supplier able to offer a
complete system combining electrical,
data and hydraulic transmission.
The reliability of the system is vital and
the 24/24 hours service, availability is
part of our strength to serve our customers navigating where ever, from
Barrents Sea to the Coral Sea, from the
North Sea to Panama, or from the
Chinese Sea to the Tasmanian Sea.
The MPS slipring system is supplied in an IP 44 heavy robust steel housing for marine use and is
pre-wired with cables or hoses according to the customer request.

Applications
The MPS sliprings are installed at the
stern of the ship and according to the
application can be single or twin, centrally
located , or port and starboard side.

Designed ,
manufactured and tested
to resist to forces of 5 G
or more and strong
vibrations, the MPS slipring
is a vital component to the
ship reliability.

In this photo of the main electrical control room, the “brain “ of the ship , we can see how the
MPS slipring system is integrated in the propulsion system of the ship in order to insure 100%
reliability on a ship carrying around 2500 passengers and crew.
